    Hi,
    I'v got a problem - I can't connect to the db from the Oracle server, tnsnames.ora and listenre.ora are identical for all servers, but I can't connect only from one of them. Listener is fine as I can connect to this server from another machines. What it might be?

    $ sqlplus system/manager@qa

    $ oerr ora 6401
    06401, 00000, "NETCMN: invalid driver designator"
    // *Cause: The login (connect) string contains an invalid driver designator.
    // *Action: Correct the string and re-submit.

    Please check your tnsnames.ora file
